Like other voting districts, school board and highway commission districts must conform to the "one person, one vote" reapportionment standard in order to be constitutionally acceptable. Most counties establish school and highway districts through private acts of the General Assembly; reapportionment of these districts must be accomplished by private act if a private act established the original districts. Many counties provide that school board districts and highway commission districts are to coincide with the county commission districts of the county. This practice can substantially simplify the reapportionment process.
